Jointly Owned Vessel, One Owner Wants Out
Two friends jointly own a 6 m cabin cruiser registered in Victoria. Both names appear on the registration. They have a falling-out. Owner A wants to sell their share to a third party and continue using the boat under a new co-ownership arrangement with the buyer. Owner B opposes any change and refuses to sign transfer paperwork. The registration renewal is due in six weeks. Owner A has paid the last two renewal fees in full from their own account; Owner B has paid nothing since purchase. There is no written co-ownership agreement. Owner A asks whether they can unilaterally transfer their share, whether they can force a sale, and what happens to the registration if the dispute is unresolved at renewal time.
1. Analyse whether Owner A can unilaterally transfer their share and change the registration, and identify what the registration authority can and cannot do.

Property interest versus registration status. These are two different things and conflating them is the classic error. Owner A's share in the vessel is a property interest governed by general law and any agreement between the owners. The registration record is an administrative record of who is responsible for the vessel. Transferring a share in the vessel does not automatically alter the register, and altering the register does not by itself transfer property.
Can A transfer their share unilaterally? A co-owner can generally deal with their own interest, but the practical ability to convey a clean, usable share is constrained by B's rights. A buyer taking a share in a jointly registered vessel where the other owner refuses to cooperate is buying into a dispute. Without a written agreement, the default position is that neither owner can exclude the other, and major decisions (sale of the whole vessel, significant alterations) typically require agreement or a court/tribunal order.
Can A change the registration alone? Almost certainly not. Where two names are recorded, the authority will normally require the signature or consent of all recorded owners to add, remove or substitute a registered owner. A cannot 'remove' B by lodging a form. The authority is not a dispute-resolution body; it will not adjudicate who is right, and it will not transfer a share on one owner's say-so over the other's objection.
What the authority can do: process a properly consented change; refuse an incomplete or contested application; and advise the parties to resolve the dispute (mediation, or an application to the appropriate court or tribunal for an order, including an order for sale and division of proceeds).
Practical step: A should put the proposal to B in writing, set a deadline, and record B's refusal. That record is the foundation for any later application for an order.
2. The dispute is unresolved at renewal. Explain the registration and fee consequences, including the relevance of A having paid prior fees alone.

Registration consequence. Renewal is a single transaction for the vessel. If the renewal is not paid by the due date, the registration lapses for the vessel as a whole - it does not lapse 'for A's half'. Neither owner can lawfully operate an unregistered vessel. B's refusal to cooperate does not protect B from that outcome; it simply means both owners lose lawful use until the renewal is sorted out. If the scheme allows late renewal within a grace period, the parties should use it, but a contested ownership position may prompt the authority to require clarification before renewing.
Fee consequence. The renewal fee is a vessel-level fee, not a per-owner fee. The authority does not apportion it between co-owners and does not care whose bank account paid it. A's payments create a private debt/contribution question between A and B, not a registration issue. A may be able to recover B's share through civil action (money paid for B's benefit, or contribution between co-owners), but that is separate from the licence authority's processes.
Risk if A pays again. If A pays the full renewal to preserve the registration, A is effectively funding B's continued access to the vessel. A should pay only if preserving registration is worth more to A than the leverage lost - and should document the payment and notify B in writing that A expects contribution.
Best sequencing: (1) pay the renewal before the due date to avoid lapse, (2) notify B in writing of the payment and demand contribution, (3) pursue resolution of the ownership dispute separately, and (4) only then lodge any consented change to the register. Letting the registration lapse to 'punish' B is self-harm, because it removes A's own lawful use and weakens A's position.
